electrical parts) of metallic particles that can cause short circuits. If combustibles are in the area, do
NOT weld or cut. Move the work if practicable, to an area free of combustibles. Avoid paint spray
rooms, dip tanks, storage areas, ventilators. If the work cannot be moved, move combustibles at
least 10m away out of reach of sparks and heat; or protect against ignition with suitable and snug
fitting, fire-resistant covers or shields. Walls touching combustibles on opposite sides should not be
welded on (or cut). Walls, ceilings, and floor near work should be protected by heat resistant covers
or shields. Fire watcher must be standing by with suitable fire extinguishing equipment during and
for some time after welding or cutting if:
a) appreciable combustibles (including building construction) are within 10m.
b) appreciable combustibles are further than 10m but can be ignited by sparks.
c) openings (concealed or visible) in floors or walls within 10m can expose
combustibles to sparks.
d) combustibles adjacent to walls, ceilings, roofs or metal partitions can be ignited by
radiant or conducted heat.
After work is done, check that area is free of sparks, glowing embers, and flames. An empty container
that held combustibles, or that can produce flammable or toxic vapours when heated, must never be
welded on or cut, unless container has first been cleaned. This includes: a thorough steam or
caustic cleaning (or a solvent or water washing, depending on the combustible’s solubility) followed
by purging and inerting with nitrogen or carbon dioxide, and using protective equipment. Water filling
just below working level may substitute for inerting. A container with unknown contents should be
cleaned (see above), do NOT depend on sense of smell or sight to determine if it is safe to weld or
cut. Hollow castings or containers must be vented before welding or cutting - they can explode. In
explosive atmospheres, never weld or cut where the air may contain flammable dust, gas, or liquid
vapours.
2. ELECTRIC ARC (MIG, TIG) WELDING
Comply with precautions in 1 above, and this section. Arc welding, properly done, is a safe process,
but a careless operator invites trouble. The equipment carries high currents at significant voltages.
The arc is very bright and hot. Sparks fly, fumes rise, ultraviolet and infrared energy radiates,
weldments are hot. The wise operator avoids unnecessary risks and protects himself and others
from accidents.
2.1 Burn protection
Comply with precautions in 1.1. The welding arc is intense and visibly bright. Its radiation can damage
eyes, penetrate lightweight clothing, reflect from light coloured surfaces and burn the skin and eyes.
Skin burns resemble acute sunburn, those from gas-shielded arcs are more severe and painful.
DON’T GET BURNED! COMPLY WITH PRECAUTIONS!
2.2 Protective clothing
Wear long sleeved clothing (particularly for gas shielded arc) in addition to gloves, hat and shoes
(see 1.1). As necessary, use additional protective clothing such as leather jacket or sleeves, flameproof
apron, and fire-resistant leggings. Avoid outer garments of untreated cotton. Protect bare skin. Wear
dark substantial clothing. Button collar to protect chest and neck and button pockets to prevent
entry of sparks.
2.3 Eye and head protection
Protect eyes from exposure to arc. NEVER look at an electric arc without protection. Welding
helmet or shield containing a filter plate shade no. 12 or denser must be used when welding. Place
over face before striking arc. Protect filter plate with a clear cover plate. Cracked or broken helmet or
shield should NOT be worn; radiation can pass through to cause burns. Cracked, broken,
or loose
